CMMS Creates The Foundation for Maintenance Excellence
A Computerized Maintenance Management System (CMMS/EAM) or Enterprise Asset Management (EAM) system is designed to manage maintenance transactions the same way an Accounting Information Management System manages financial transactions. In the case of maintenance, the transactions are work orders instead of invoices. Inventory is the work backlog and spare parts instead of raw material used in manufacturing.
Accurate information is critical to making decisions that ensure the reliable operation of equipment. Developing strategies and tactics for ensuring equipment function can be made easier with accurate maintenance transaction details. Summary reports allow maintenance managers to spot troublemakers; the “critical few” trouble spots that are causing the greatest problems. Planning and scheduling jobs can also be more effective with a fully functional CMMS/EAM. Although creating a proactive maintenance culture is possible without a functional CMMS/EAM, it is very rare.

Maintenance Tip
Maintenance Welding Can Cause Equipment Failures
Maintenance Welding can cause premature failure of equipment and/or systems. Many maintenance professionals know how to weld and many have been certified in welding but very few understand maintenance welding. In order to understand maintenance welding you must be fluent in the fundamentals of welding.
Listed below are maintenance tips for personnel performing Maintenance Welding. These welding tips are focused mainly on the use of Shield Metal Arc Welding (typically called stick or arc welding) process.
• Use only a E6010 and E6011 electrode for welding on dirty metal
• Use E7018 or higher for clean metal when higher strength is important
• Use E6013 for thin metal such as sheet metal only (no penetration properties)
• Use E6011 5P for welding a pipe root pass. Be sure and leave a 1/8” gap for the root (do not use E7018 for the root pass)
• Use reverse stitch welding for welding on metal that may become distorted from the welding
• Always use a certified welder when welding on high pressure pipe or fork trucks
• For a welder to be “certified” he/she must meet specific requirements set forth by the American Welding Society and other agencies
• Welding certification can only be used for a specific company and must be updated yearly
• Do not use specialty electrodes with the exception of use for hard facing metal and cast iron as a general rule. Most maintenance welding can be performed using E6010, E 6011, E7018, and E6013 electrodes which are less expensive
• We recommend you provide training in welding for all of your maintenance staff that welds (this course depends on the type welding process you use in your facility) (ASK ME WHAT OSHA SAYS about training for personnel who weld)

Vibration Analysis Tip
Collecting Good Data 4 of 6 – Test Frequency
Tips 1-3 archived at http://maintenancetalk.com/blog.php/tipsblog/
Testing machines too often costs money and wastes resources. Testing machines too infrequently can result in missed faults and catastrophic failures. The key is to find the middle ground and this will depend on the machine, its history and its criticality. Some high speed machines can devolve from perfect health to failure in a matter of minutes. These will require continuous monitoring protection systems. Other machines may run for years without problems. These should be tested quarterly or biannually with test frequency increasing as incipient faults begin to appear. Although a small pump may be inexpensive to repair or replace, if its failure causes a million dollars of product to be ruined, it can be said to be quite critical and worthy of more frequent testing.
The best approach is to spend some time researching the machines, their history and their use. Understanding how the machines fail often gives some indication of how long it will take them to fail after faults begin to appear. A good deal of resources can be saved and better appropriated if records are kept over time and the schedule adjusted as more machinery history and knowledge becomes available.

Maintenance Tip
Never substitute a missing bolt without making sure that it is the correct bolt for the application. The maintenance manual should have the correct information and the bolt head marking should verify the bolt particulars. Sometimes because of work pressure people will replace a bolt without checking, just to hurry and complete the work.

Utilizing a CMMS to Develop and Support Key Maintenance Performance Indicators by Terry Wireman
CMMS-2005 Pre-Conference Workshop
Computerized Maintenance Management Summit
July 26-29, 2005
Indianapolis Indiana
This workshop not only instructs on the use of basic indicators for managing maintenance and how to link them to a company’s financials, it addresses further advancements in the management of maintenance.
The Developing Performance Indicators for Managing Maintenance workshop utilizes techniques based on other management measurement systems, such as the balanced scorecard. What’s more it presents a maturing of measurement technique for maintenance and asset maintenance and development techniques that will allow companies to be competitive into the future. It is a necessary learning event for any company that has a maintenance organization to learn how to effectively measure and manage the entire spectrum of maintenance activities.
Workshop attendees each receive a hardcover copy of Developing Performance Indicators For Managing Maintenance as part of the one day course.
Join Terry plus more than 35 other presenters, workshop leaders and learning labs directors at CMMS-2005.

The 29th Annual Meeting - Vibration Institute
June 13-17, 2005
Omni Richmond Hotel
Richmond, Virginia
The Vibration Institute will conduct its 2005 National Technical Training Symposium (formerly termed the Annual Meeting) in Richmond from June 13 through June 17 at Omni Richmond Hotel. The purpose of the Symposium is to provide specific training in practical vibration technology.

Airborne Ultrasound Tip
When corona is detected during a closed door switchgear inspection, after appropriate safety precautions, be sure to slowly open door as to keep the environment inside from moving. Moving particles inside can cause the corona activity to stop. Making is difficult to again spot the corona with the airborne ultrasonic detector. Some corona activity can be the results of dust or contamination around sharp edges of bakelite and/or upon insulators, movement of the air or environment internally may cause this dusting or particles to release.

Motor Testing Tip
The cause of current unbalance can be quickly identified in three phase systems. The process is referred to as ‘rotating phases.’ The trick is to identify the current readings of each phase, such as: A = 10 Amps; B = 12 Amps; and, C = 15 Amps. You then switch the conductors such that phase A is moved to phase B, phase B is moved to phase C and phase C is moved to phase A. This preserves the rotation of the motor. Restart the motor and re-measure current.
If the current balance remains the same, with the A, B and C phase currents remaining low, medium and high, then the unbalance is due to the motor. If the unbalance rotates such that A = 15, B = 10 and C = 12 (or close), then the current unbalance is due to the power supply.

Vibration Analysis Tip
To help justify your vibration analysis program, try providing your machinery’s health in a report. Print out a statistical report showing how many pieces of equipment are within acceptable limits versus how many are outside acceptable limits. Often, you think management only wants to see the bad equipment, but one of the major benefits is showing a problem in its infancy, before the failure.
